Specification of Letters Patent.

'Batenflt'ed 1060.15, 191d.

Application filed March 22, 1920. Serial No. 550355.

To all whom it may concern Be it known that I, Enxns r B. BISHOP, aioitize-n of the United'St-ates, residing at Middletown, in the county of liiiddlesex and State of Connecticut, have invented certain new and useful Improvements in Type- W-nitim; Machines, of which the following is a fun, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to typevvriting machines, and with regard to the more specific features thereof, .to space bar mechanism.

Gne of the objects of the present invention is to provide a simple and practical device which will be efficient in operation.

Another chest is to construct a device of the above nature which will be silent in its operation.

A further object is to provide a device of the above nature which will permit an easy action and a substantially vertical movement of the space bar.

A further object is to provide .a device of the above nature of a few number of parts that will be cheap to manufacture.

A further object is to provide for a uniformity of action among the moving parts.

Other objects will be in part obvious and in part herein-after pointed out.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, wherein is shown one of many possible embodiments of the present invention, Figure 1 represents a side elevation of a typewriter sufficient to illustrate an embodiment of the present invention applied thereto; Fig. 2 is a plan view of the same.

Similar reference characters refer to similar parts throughout the several views of the drawings.

lvVhile the present invention is illustrated and described with reference to that form of a typewriting' machine known as the Noiseless typewriter, it is, of course, to be understood that the mechanism illustrated and described herein *mey be applied to any tor-1n of a typewriter without materially altering or modifying the construction.

Referring to these drawings in detail, 1 rep-resents a space bar locaited in front -:of the key board supportcdby space bar levers 2 and 3 which pass below the various actuating parts of the machine to substantialry the rear of the frame, where they are ful crmned on pins -i supported by depending lugs 5 and 6 secured to the frame of the machine. Intemnediate the arms 2 and 3 is positioned .a cross brace 7 for "stiifness and also furnishing a means of connection tor a pull wire secured at one end 9 thereto and to a tfalse key or spacing lever 10 at the point J1. A. clip 12 is provided for-holding the end of the pull Wire 8 in engagement with the spacing lever 10. This lever 10 is fulcrunacd at one end on alknife edge -13 after passing through a slot in a comb 1+ and is securely held in place by means of a pivoted roller 1.5 suspended from brackets 16 .at either side of the slot to prevent-Innsplacement at this point when the space bar is actuated. A spring 1? is adj'ustably mounted at one \end in the comb and inserted through a hole in the spacing; lever 10 for holding the same in normal position. It is to be noted that this spring aids in returning the parts to normal position when the same have been actuated by the space bar.

The lever 10 1s similar in general construction to any -.key lever, only-one of which, 10, isshown, and is guided in a vertical direction at its forward end by means of a comb 18 for the key levers secured .0 any convenient part of the frame'of the machine. It is provided with a foot 19 adapt ed to contact with a pad 20 mounted on a universal bar 21 when the lever is actuated A slight space is preferably provided between the foot of the spacing lever 10 and the pad .20 on the universal bar, as Well as between the key levers 10 and the pad, to prevent a'contact with the others when actuated by one, thereby preventing a .needless rattle and jar of the key levers at eachimpression.

The space barsand spacing lever being connected by pull wire -8 will actuate the universal bar in the same manner as the actuation of the key lever 10?, thereby givizng a uniformity of action among those moving .parts. This universal bar: maybe of any desired construction, but that form illustrated and described in the pending application of J. A. Ronchctti, Serial No. 436,749, filed June 5, 1908, for typewriting machines, with the silent stop shown therein, is believed to be especially advantageous for use in this relation. The lower part of this universal bar is provided with a pad 22 adapted to engage a bracket 23 secured to the frame in such manner that it is per mitted to have :1 rec and unrestricted movement in a. downward direction and yet be silently arrested on its return to normal position. The arms and 3 of the space bar are each provided with upwardly projec'ting foot 2% adapted to engage pads or other silencing means 25 secured to the frame immediately behind the brackets 28. These spacing levers 2 and 3 are guided in their vertical movement by means of slots in theunder side of the comb l8.

A stop 26 securedto the forward part of the frame is preferably provided for the space bar to silently arrest the same on its downward movement. This stop may be made adjustable as at 2? if desired, should it be found necessary to adjust the stroke at any time. The universal bar 21 is suspended by means of links 28 from arms 29 rigidly secured to the universal rock shaft 30. Projecting rearwardiy from this rock shaft and also secured rigidly thereto is an arm 31 connected by means of a spring with any convenient fixed part of the machine 33 for normally holding the universal. bar and as sociated parts in raised position. A third arm on the universal rock shaft 80 is adapted to be connected to the vibratory rccl-ier member of the spacing mechanism, which it is believed is unnecessary to illustrate in this application.

The operation and manner of use of this device is substantially as follows: The space bar 1 being positioned at such a relatively large distance from its pivot point, it moves in almost a vertically straight line w icn depressed and carries withit the spacing lever 10, which is connected therewith by means of the pull wire 8. W hen the spacing lever is depressed the foot 19 contacts silently with the pad on the universal bar 21 and depresses the same to actuate the universal rock shaft 30, which, through connecting mechanism, actuates the spacing mechanism, not herein shown. "hcn the'spacing lever 10 is do essed the spring 1,? will be tensiimed, and also the spring 32- connected with the arm upon the uni\ rsal rock shaft. These sprii'igs will aid one another in return air the parts to nornisal position as soon as 1 the bar 1 is re- 'sal posh tlonil. Mn Cnntact on he frame of :31 at the lower part of the universal bar 21 will contact with the bracket 23 on a fixed part of the machine in such manner as to silently arrest both of these parts. provided between the upper surface of the pad 20 on the universal bar and the key levers and spacing lever 10 prevents the same from coming in contact therewith to cause needless rattle and jar of the actuating parts.

It is thus seen that this invention provides for a simple and practical construction in which the space bar has an almost vertical movement due to the fact that its pivot is at the rear of the frame of the machine and the are through which it tra els is therefore almost imperceptible. Various silencing means associated With the actuating parts of the mechanism enable the spacing mechanism to be actuated withoutnoise and in. a speedy and eliicient manner.

As many changes could be made in the above construction and many apparently Widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the acompanying drawingsshall be interpreted as illustrative and not in a limiting sense. 4
